From dailyzen.com:
“As you go along practicing turning the light around, you need not give up your normal occupation. An ancient said, “When matters come up, one should respond; when things come up, one should discern.” If you manage your affairs with accurate mindfulness, then the light is not overcome by things, so it will do to repeat this formless turning around of the light time and again. If you can look back again and again into the source of mind, whatever you are doing, not sticking to any image of person or self at all, then this is “turning the light around wherever you are.” This is the finest practice.”
